Endocrine therapy (ET) has benefited patients with estrogen receptor alpha (ERα) pos. breast cancer for decades. Selective estrogen receptor modulator (SERM) such as Tamoxifen represents the clin. standard of care (SoC). Despite the therapeutic importance of current SoC agents, 30-50% of prolonged treatment patients inevitably generated resistant tumor cells, usually eventually suffered tumor relapse and developed into metastatic breast cancer (MBC), which was the leading cause of female cancer-related mortality. Among these, most resistant tumors remained dependent on ERα signaling, which reignited the need for the next generation of ERα related agents. Authors hypothesized that selective estrogen receptor covalent antagonists targeting ERα would provide a therapeutic alternative. In the current work, series of novel benzothiophene hybrids I (R₁ = H, Me; R₂ = Me; R₁R₂ = (CH₂)₃, (CH₂)₅, etc.) II, III (R₃ = R₄ = H, Me) and IV bearing electrophile moieties were synthesized and biol. evaluated. The representative analog I (R₁R₂ = (CH₂)₃) exhibited potent anti-proliferative effect in MCF-7 cell lines in vitro, and further mechanism studies confirmed the necessity of covalent bonding. More importantly, I could attenuate the expression of TFF-1, GREB-1 and down-regulate the levels of cellular ERα protein. This study involved multiple reactions and reactants, such as 4-Benzyloxyphenol (cas: 103-16-2COA of Formula: C13H12O2).

4-Benzyloxyphenol (cas: 103-16-2) belongs to ethers. Carboxylic acid esters of low molecular weight are colourless, volatile liquids with pleasant odours, slightly soluble in water. Many esters have the potential for conformational isomerism, but they tend to adopt an s-cis (or Z) conformation rather than the s-trans (or E) alternative, due to a combination of hyperconjugation and dipole minimization effects. The preference for the Z conformation is influenced by the nature of the substituents and solvent, if present. Lactones with small rings are restricted to the s-trans (i.e. E) conformation due to their cyclic structure.COA of Formula: C13H12O2

Decarboxylative amination of benzoic acids bearing electron-donating substituents and nonactivated amines was written by Wang, Feilong;Han, Ying;Yu, Le;Zhu, Dianhu. And the article was included in Organic Chemistry Frontiers in 2022.Electric Literature of C12H12N2O The following contents are mentioned in the article:

A highly desirable and straightforward decarboxylative amination of readily available benzoic acids, with the long-inaccessible extension of decarboxylative amination to normally poorly reactive electron-rich benzoic acids and non-activated amines for synthesis of anilines RNR¹R² [R = 2-MeOC₆H₄, 2,6-di-MeC₆H₃, 2-methoxy-3-pyridyl, etc.; R¹ = H, Me; R² = Ph, Bn, 2-naphthyl, etc.; R¹R² = CH₂CH₂OCH₂CH₂] in moderate to high yields with excellent functional-group tolerance was reported. This aniline synthesis was applicable to a wide range of aryl/alkyl/heterocyclic amines under oxidant-free conditions, preventing adverse reactions compared to traditional methods. It also provided decarboxylative C-N modifications of complex bioactive nitrogen-bearing mols. to highlight the synthetic utility of this protocol. The theor. calculation had supported that this decarboxylative amination might proceeded via a concerted decarboxylation-iodination-type process to afford aryl iodine intermediates, which promoted a palladium-catalyzed C-N cross-coupling pathway under mild conditions. Notably, this efficient reaction featured a fine choice of the same base/solvent system to successfully achieve two independent reactions in a one-pot continuous operation process. This strategy provided a method for previously inaccessible decarboxylative amination of benzoic acids bearing electron-donating substituents, as a new alternative to the existing decarboxylative oxidative couplings. This study involved multiple reactions and reactants, such as N-(4-Methoxyphenyl)pyridin-3-amine (cas: 562085-85-2Electric Literature of C12H12N2O).

N-(4-Methoxyphenyl)pyridin-3-amine (cas: 562085-85-2) belongs to ethers. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits. Because of their lack of hydrogen-bond-donating ability, esters do not self-associate. Consequently, esters are more volatile than carboxylic acids of similar molecular weight.Electric Literature of C12H12N2O

Imine based chiral liquid crystals: Effect of varying the terminal substituent and orientation of ester linking unit was written by Karanlik, Gurkan;Ocak, Hale;Bilgin Eran, Belkiz. And the article was included in Journal of Molecular Liquids in 2019.Related Products of 103-16-2 The following contents are mentioned in the article:

New liquid crystalline compounds composed of three-benzene-ring mol. core comprising both the imine and ester linkage units, (S)-3,7-dimethyloctyloxy chiral unit at one of terminals and n-dodecyl/dodecyloxy group as other side chain have been synthesized and characterized to study the effect of varying terminal chains, the orientation of polar ester linking group and the presence of mol. chirality on mesophase properties of imine based calamitic compounds The liquid crystalline properties of the compounds were investigated by differential scanning calorimetry, optical polarizing microscopy and electro-optic methods. As a result of the strong effect of chirality of (S)-3,7-dimethyloctyloxy chain, all Schiff bases (imines) exhibit enantiotropic chiral smectic C (SmC*), chiral nematic (N*) as well as SmX phase just below the SmC* phase and blue phase (BP) appearing monotropically. The SmC* phase shows ferroelec. switching behavior with P_S values in the range 70-130 nC cm^-2. The alteration of the n-alkyl tail with an alkoxy chain gives rise to a significant increase up to 30 °C in mesomorphic transitions. The change in the orientation of polar ester linking group has no effect on the type and sequence of observed LC phase. As compared with (S)-4-(3,7-dimethyloctyloxy)phenol based imine derivatives (7a, 7b), the chiral nematic (N*) mesophase temperature range of (S)-4-(3,7-dimethyloctyloxy)benzoate based compounds (8a, 8b) significantly broadened. Addnl., a decrease on the phase transition temperatures occurred with regardless of introducing n-dodecyl/dodecyloxy group as side chains.

Autologously transplanted dermis-derived cells alleviated monobenzone-induced vitiligo in mouse was written by Erdogan, Asli;Mutlu, Hasan Serdar;Solakoglu, Seyhun. And the article was included in Experimental Dermatology in 2022.Synthetic Route of C13H12O2 The following contents are mentioned in the article:

Vitiligo is a depigmentation disease which affects skin and hair follicles with a prevalence of 0.5%-1% worldwide. In this study, we aimed to investigate treatmental potential of dermis-derived cells in monobenzone (MBEH)-induced mouse vitiligo model with light and electron microscopy. MBEH (40%) cream was topically applied to C57BL/6 mice until depigmentation occurred in vitiligo and exptl. groups. In exptl. groups, dermis-derived cells obtained from back skin biopsy samples before induction of vitiligo, were injected intradermally to vitiligo mice. On Days 3 and 15 after cell transplantation to exptl. groups, skin biopsies were compared with biopsies of control and vitiligo groups. Dermis-derived cells obtained from back skin biopsy samples of exptl. groups showed nestin and versican immunoreactivity. Melanin in hair follicles of control group was detected by histochem. stainings (Haematoxylin and eosin and Fontana-Masson) whereas sparse melanin granules were observed in hair follicles of vitiligo group. In exptl. groups, there was an increase in the number of hair follicles with melanin compared with vitiligo group. We observed MART-1 immunoreactive cells mostly around the hair follicles in control group and within dermis in vitiligo group. Electron microscopic investigation showed presence of melanosomes in hair follicles of control group and lacking in vitiligo group. In exptl. groups, both type of hair follicles were observed with electron microscope. Our data suggest that autologously transplanted dermis-derived cells may be effective in vitiligo treatment by contrubuting to melanin production This study involved multiple reactions and reactants, such as 4-Benzyloxyphenol (cas: 103-16-2Synthetic Route of C13H12O2).

4-Benzyloxyphenol (cas: 103-16-2) belongs to ethers. Esters typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones. Esterification is the general name for a chemical reaction in which two reactants (typically an alcohol and an acid) form an ester as the reaction product.

Overall survival of patients with low-grade glioma (LGG) has shown no significant improvement over the past 30 years, with survival averaging approx. 7 years. This study aimed to identify novel promising biomarkers of LGG and reveal its potential mol. mechanisms by integrated bioinformatics anal. The microarray datasets of GSE68848 and GSE4290 were selected from GEO database for integrated anal. In total, 293 overlapping differentially expressed genes (DEGs) were detected using the limma package. One hundred and eighty-eight nodes with 603 interactions were obtained from the establishment of protein-protein interaction (PPI) network. Functional and signaling pathway enriched were significantly correlated with the synapse and calcium signaling pathway, resp. Module anal. revealed eight hub genes with high connectivity, which included CHRM1, DLG2, GABRD, GRIN1, HTR2A, KCNJ3, KCNJ9, and NUSAP1, and they were markedly correlated with patients′ prognosis. The mining of the Gene Expression Profiling Interactive Anal. database and qPCR further confirmed the abnormal expression of these key genes with their prognostic value in LGG. We eventually predicted the 20 most vital small mol. drugs, which potentially reverse the carcinogenic state of LGG, as per the CMap (connectivity map) database and these DEGs, and MS-275 (enrichment score = -0.939) was considered as the most promising small mol. to treat LGG. In conclusion, our study provided eight reliable novel mol. biomarkers for diagnosis, prognosis prediction, and treatment targets for LGG. These conclusions will contribute to a better comprehension of mol. mechanisms fundamental to LGG occurrence and progression, and providing new insights for future development of genomic individualized treatment in LGG. This study involved multiple reactions and reactants, such as 4-Benzyloxyphenol (cas: 103-16-2SDS of cas: 103-16-2).

4-Benzyloxyphenol (cas: 103-16-2) belongs to ethers. Volatile esters with characteristic odours are used in synthetic flavours, perfumes, and cosmetics. Certain volatile esters are used as solvents for lacquers, paints, and varnishes. Esters are more polar than ethers but less polar than alcohols. They participate in hydrogen bonds as hydrogen-bond acceptors, but cannot act as hydrogen-bond donors, unlike their parent alcohols. This ability to participate in hydrogen bonding confers some water-solubility.SDS of cas: 103-16-2

Antagonists for Constitutively Active Mutant Estrogen Receptors: Insights into the Roles of Antiestrogen-Core and Side-Chain was written by Sharma, Abhishek;Toy, Weiyi;Guillen, Valeria Sanabria;Sharma, Naina;Min, Jian;Carlson, Kathryn E.;Mayne, Christopher G.;Lin, Shengjia;Sabio, Michael;Greene, Geoffrey;Katzenellenbogen, Benita S.;Chandarlapaty, Sarat;Katzenellenbogen, John A.. And the article was included in ACS Chemical Biology in 2018.Reference of 103-16-2 The following contents are mentioned in the article:

A major risk for patients having estrogen receptor α (ERα)-pos. breast cancer is the recurrence of drug-resistant metastases after initial successful treatment with endocrine therapies. Recent studies have implicated a number of activating mutations in the ligand-binding domain of ERα that stabilize the agonist conformation as a prominent mechanism for this acquired resistance. There are several critical gaps in our knowledge regarding the specific pharmacophore requirements of an antagonist that could effectively inhibit all or most of the different mutant ERs. To address this, we screened various chemotypes for blocking mutant ER-mediated transcriptional signaling and identified RU58668 as a model compound that contains structural elements that support potent ligand-induced inhibition of mutant ERs. We designed and synthesized a focused library of novel antagonists and probed how small and large perturbations in different ligand structural regions influenced inhibitory activity on individual mutant ERs in breast cancer cells. Effective inhibition derives from both nonpolar and moderately polar motifs in a multifunctional side chain of the antagonists, with the nature of the ligand core making important contributions by increasing the potency of ligands possessing similar types of side chains. Some of our new antagonists potently blocked the transcriptional activity of the three most common mutant ERs (L536R, Y537S, D538G) and inhibited mutant ER-mediated cell proliferation. Supported by our mol. modeling, these studies provide new insights into the role of specific components, involving both the ligand core and multifunctional side chain, in suppressing wild-type and mutant ER-mediated transcription and breast cancer cell proliferation.

Lignin is an abundant source of aromatics, and the depolymerization of lignin provides significant potential for producing high-value chems. Selective hydrogenolysis of the C-O ether bond in lignin is an important strategy for the production of fuels and chem. feedstocks. In our study, catalytic hydrogenolysis of lignin model compounds (β-O-4, α-O-4 and 4-O-5 model compounds) over Ni₃S₂-CS catalysts was investigated. Hence, an array of 2D carbon nanostructure Ni₃S₂-CSs-X-Y derived catalysts were produced using different compositions at different temperatures (X = 0 mg, 0.2 mg, 0.4 mg, 0.6 mg, and 0.8 mg; Y = 600°C, 700°C, 800°C, and 900°C) were prepared and applied for hydrogenolysis of lignin model compounds and depolymerization of alk. lignin. The highest conversion of lignin model compounds (β-O-4 model compound) was up to 100% and the yield of the obtained corresponding ethylbenzene and phenol could achieve 92% and 86%, resp., over the optimal Ni₃S₂-CSs-0.4-700 catalyst in iPrOH at 260°C without external H₂. The 2D carbon nanostructure catalysts performed a good dispersion on the surface of the carbon nanosheets, which facilitated the cleavage of the lignin ether bonds. The physicochem. characterization studies were carried out by means of XRD, SEM, TEM, H₂-TPR, NH₃-TPD, Raman and XPS analyses. Based on the optimal reaction conditions (260°C, 4 h, 2.0 MPa N₂), various model compounds (β-O-4, α-O-4 and 4-O-5 model compounds) could also be effectively hydrotreated to produce the corresponding aromatic products.
